Just received my cards a few days ago and I’ve played it several times now with my family. It is a somewhat complex but definitely fun game to play. Someone playing can’t help but learn something about STEM and something about the historical figures who helped shape it. As a professor of materials science and engineering, I would endorse this for an after school activity for late elementary/middle school and beyond. Also, it is a fun game in general for anyone. The artwork is exceptional as well.
